With tremendous advancement in digital technology, efficient steganography techniques are
needed for the security and copyright protection of digital information being transmitted over …

Least Significant Bit (LSB) technique is the earliest developed technique in watermarking
and it is also the most simple, direct and common technique. It essentially involves …

Watermarking is a data authentication technique which embeds the watermark data within
the original image in order to claim for copyright protection. Watermark techniques must be …

Prior research studies have shown that the peak signal to noise ratio (PSNR) is the most
frequent watermarked image quality metric that is used for determining the levels of strength …

In this present work, we propose a new reversible color image watermarking technique,
using trigonometric functions. The proposed method embeds secret bits into the gray planes …

The most important requirements should be available on any watermarking systems which
are the robustness against possible attacks and the quality of the watermarked images. In …

This paper presents a robust blind frequency domain watermarking scheme based on
chaotic maps. The proposed scheme embeds a black and white watermark logo in the …

In this paper, a novel data-hiding technique based on the Fibonacci representation of digital
images is presented. A generalization of the classical Least Significant Bit (LSB) embedding …

In this paper, the authors have proposed a binary watermark embedding approach for
protecting the copyright ownership of the gray-scale images. The proposed watermark …
